Here is the mask if you want to build it by yourself (600 dpi, 1 layer): I moved the PWM0 and PWM1 pins to the right side for a easier rooting on 1 layer.

Here are the gerber files, if you want order to a PCB fusion company (for example seeedstudio with 3 "e"), i changed for a 2 layer PCB, with this you will have the 2 pins PWM0 and PWM1 at the correct place :Preview :
